The ash sanctifier is a reward from completing the Hard Kourend & Kebos Diary, where players can then claim it from Tyss. To use it, it must be charged with death runes, gaining 100 charges per death rune.
When charged and carried in the inventory, if the player kills a monster that drops demonic ashes, the ash sanctifier will automatically purify demonic ashes that are dropped from demonic creatures, granting the player half the Prayer experience they would have received from scattering the ashes themselves, consuming one charge in the process. This effect can be toggled with the right-click "Activity" option.
- This item was initially named as the "Ash scatterer" in the original poll blog, but was changed to "Ash sanctifier" after player feedback.
